Grams of fuel per kilonewton-second to pounds of fuel per pound-force per hour
Type a value in g/(kN·s) to get it in lb/(lbf·h) instantly.
12.36lb/(lbf·h)
That's 1.03× as efficient as a Merlin engine at sea level, while a Merlin vacuum engine is 1.19× more efficient. Its exhaust leaves at about 2.857 km/s.
What it means
How efficient is that engine?
Rocket figures are typical published values, at sea level unless marked vacuum. The jet-engine figure is for an airliner at cruise.
The math
How to convert g/(kN·s) to lb/(lbf·h)
Effective exhaust velocity is Isp × 9.80665. Thrust-specific fuel consumption in lb/(lbf·h) is 3,600 ÷ Isp.
Example: 350 g/(kN·s) = 12.3564 lb/(lbf·h).

About these units
Grams of fuel per kilonewton-second (g/(kN·s))
Metric thrust-specific fuel consumption.
Pounds of fuel per pound-force per hour (lb/(lbf·h))
Jet-engine fuel consumption, the inverse of specific impulse. Lower is better.
